Oh, and natural reds tend to run coarse from what I've read, but there are many fine haired redheads out there. Hair color and thickness trends don't always work. Fine, blonde hair is stereotypical, yet there are coarse haired blondes, too.
The redheads in my family have what my sister calls 'boy hair'. Coarse strand that don't feel silky. I can hear my hair when I rub it. It's crinkly.
Med/Coarse, porous curly.
